Description

Technical Field

[0001] The present invention relates to the technical field of neural network circuits, and in particular to an emotion habituation neural network circuit with context dependence and generalization. Background Art

[0002] As an emerging nanoscale electronic device, memristors have been widely used in logical operations, secure communications, biological behavior simulation, analog circuits, and other fields, and have great application prospects. The variability and non-volatility of memristor resistance are very similar to synaptic characteristics. Memristors can be used to simulate biological synapses to construct neuromorphic circuits and realize biological learning and memory functions.

[0003] Associative learning and non-associative learning are two common learning modes in organisms. Associative learning refers to the co-occurrence of two stimuli, and after a period of time, the two stimuli will become associated. Non-associative learning refers to the behavior change caused by the repeated presentation of a single stimulus. There are two main learning modes of non-associative learning, namely habituation and sensitization (dehabituation). Some scholars have proposed neural network circuits based on memristor habituation and dehabituation, but have not considered the factors that affect habituation and the generalization of habituation. The neural network circuit proposed in the present invention solves these problems. Summary of the invention

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) On the basis of the original behavioral habituation, the emotion control module transforms the previously applied single repetitive stimulus into an emotional stimulus, which is divided into positive emotion stimulus, neutral emotion stimulus, and negative emotion stimulus. Different emotional stimuli will affect the speed of habituation. This behavior of showing different emotional responses to repeated positive and negative stimuli is in line with biological characteristics.

[0027] (2) Considering the impact of the situation on habituation, the situational information is controlled by the situational control module. When the situational information changes, the habituation phenomenon will reappear. If the situational information remains unchanged, habituation will occur again after a period of time.

[0028] (3) The generalization phenomenon of habituation is taken into consideration. Through the generalization module, two similar stimuli can be habituated, which is in line with biological characteristics.

[0029] The present invention realizes two learning modes of habituation and dehabituation in biological non-associative learning through a habituation module and a generalization module, and on this basis realizes that two similar stimuli can habituate the organism. In addition, the present invention divides the nature of the stimulus into positive, neutral, and negative through an emotion control module, which respectively accelerates, maintains, and slows down the speed of habituation of the biological organism. The present invention realizes through a situation control module that when the situation information changes, the habituated response will be slightly changed, and the response will habituate again after a period of time.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] like Figure 1As shown, an emotion habituation neural network circuit with context dependence and generalization includes input signal terminals N1-N5, a habituation module I, a generalization module, an emotion control module I, a context control module I, a habituation module II, an emotion control module II, a context control module II and an output signal terminal. The input signal terminal N1 representing the stimulus signal is connected to the habituation module I, the generalization module, the emotion control module I, and the situation control module I respectively; the input signal terminal N3 representing the situation control signal is connected to the situation control module I; the generalization module, the situation control module I, and the situation control module I are all connected to the habituation module I; the output terminal of the habituation module I is an output signal terminal; the input signal terminal N5 representing the emotion control signal is connected to the emotion control module I and the emotion control module II respectively; the input signal terminal N2 representing the stimulus signal is connected to the habituation module II, the generalization module, the emotion control module II, and the situation control module II respectively; the input signal terminal N4 representing the situation control signal is connected to the situation control module II; the generalization module, the emotion control module II, and the situation control module II are all connected to the habituation module II, and the output terminal of the habituation module II is another output signal terminal.

[0042] The habituation module is to realize the habituation and dehabituation learning modes in biological non-associative learning. The generalization module is to make two similar stimuli habituate the biological body. The emotion control module is to add emotion to the original stimulus to change the speed of habituation. The situation control module is to realize that when the situation information changes, the habituated response will change slightly. After a period of time, this weak response will habituate again. The input signal terminals N1 and N2 are input stimulus signals, N3 and N4 are situation control signals, and N5 is emotion control signal. In the specific implementation, the amplitude of the input stimulus signal is 1V, and the amplitude of the situation control signal is 0V and 2.5V. The two voltage values ​​represent different situations respectively. The amplitude of the emotion control signal is 0V, 1V, and -1V, representing neutral stimulus, positive stimulus, and negative stimulus respectively. The output signal terminal is the output terminal of the habituation module.

[0043] The input signal terminal N1 is connected to the habituation module I, and the input signal terminal N2 is connected to the habituation module II. The output of the habituation module will change according to the change of the input signal terminal N1 / N2. When the input signal terminal N1 / N2 is a single repeated weak stimulus, the amplitude of the output voltage will become smaller and smaller. When a strong stimulus is input to the input signal terminal N1 / N2, the output voltage will return to the original amplitude. The input signal terminal N1 and the input signal terminal N5 are both connected to the emotion control module I, and the input signal terminal N2 and the input signal terminal N5 are both connected to the emotion control module II. The output of the emotion control module is determined by the input signal terminal N1 / N2 and the input signal terminal N5. The input signal terminal N1 and the input signal terminal N2 are both connected to the generalization module. The generalization module ensures that when the input signal terminal N1 and the input signal terminal N2 have signals at the same time, the two will be generalized. The input signal terminal N1 and the input signal terminal N3 are both connected to the situation control module I, and the input signal terminal N2 and the input signal terminal N4 are both connected to the situation control module II. The situation control module I and the situation control module II ensure that when the situation control signal N3 / N4 changes, the habituation reaction will change. The input signal terminal N5 is respectively connected to the emotion control module I and the emotion control module II; the situation control module I is connected to the habituation module I; the emotion control module I is connected to the habituation module I; the generalization module is respectively connected to the habituation module I and the habituation module II; the situation control module II is connected to the habituation module II; the emotion control module II is connected to the habituation module II.

[0044] like Figure 2 As shown, the habituation module I includes a synaptic neuron circuit I, a feedback regulation circuit I, a voltage summing unit SUM1 and a voltage summing unit SUM3. The input signal terminal N1 is connected to an input terminal of the voltage summing unit SUM1, the output terminal of the voltage summing unit SUM1 is connected to the synaptic neuron circuit I through the voltage summing unit SUM3, and the output terminal of the synaptic neuron I is connected to the feedback regulation circuit I; the input signal terminal N1 is connected to the feedback regulation circuit I, and the feedback regulation circuit I is connected to the other input terminal of the voltage summing unit SUM1. The output terminal of the generalization module is connected to the feedback regulation circuit I, and the output terminal of the emotion control module I is connected to the feedback regulation circuit I. That is, the output signal U2 and the output signal U3 of the emotion control module I are respectively added to the voltage summing unit SUM5 and the memristor M5. Since the amplitude of the input signal terminal N1 is certain, the output of the operational amplifier OP7 is only determined by the memristor M3, so the function of the synaptic neuron circuit I is to output voltages of different amplitudes according to the different resistance values ​​of the memristor M3.

When the strong stimulus applied to the memristor M3 returns to the original weak stimulus, the habituation process will occur again.

[0072] Figure 7 is the simulation result of habituation generalization, where N1 inputs the stimulus signal, M3 is the memristor, and V OUT1 is the output signal corresponding to the input stimulus N1, N2 is another input stimulus signal, M4 is the memristor, V OUT2 is the output signal corresponding to the input stimulus N2. Figure 7 It can be seen that the first 32 seconds is the test process of N1 input stimulation signal, which is determined by V OUT1 The results show that N1 input stimulation can make the output habituated. 32s-64s is the test process of N2 input stimulation signal, which is composed of V OUT2 The results show that N2 input stimulation cannot cause the output to become habituated. 64s-68s is the dehabituation process. 68s-80s is the learning process, when N1 and N2 apply signals at the same time. When learning is completed, applying N2 stimulation signals will cause the output to become habituated.

[0073] Figure 8 The simulation results of habituation under different situations and emotions are shown in Figure 2. N1 is the input stimulus signal, and N5 is the emotion control signal. When N5 is 1V, it means that positive emotion stimulus is applied at this time. When N5 is -1V, it means that negative emotion stimulus is applied at this time. When N5 is 0V, it means that neutral stimulus is applied at this time. N3 is the situation control signal. When its amplitude changes from 1V to 2.5V, it means that the situation has changed. M3 is the memristor. V OUT1 is the output signal corresponding to the input stimulus N1. As can be seen from the figure, the first 60s is the habituation process under neutral stimulation, 60-64s is the dehabituation process, and 64s-88s is the habituation process under positive emotional stimulation. When the situational information changes at 86s, the output will change and habituation will occur again after a period of time. After 128s, it is habituation under negative emotional stimulation. As can be seen from the simulation result diagram, the speed of habituation under different emotional stimulations is different. Among them, the habituation speed under positive emotional stimulation is the fastest, followed by neutral stimulation, and the habituation speed under negative emotional stimulation is the slowest.

[0074] Fig. 9 This is a complete simulation result diagram, 0s-60s is the habituation process under positive emotional stimulation, 60s-64s is the dehabituation process, 64s-148s is the habituation process under negative emotional stimulation, 148s-152s is the dehabituation process, 152s-164s is the learning process of habituation generalization, 164s-212s is the generalization process, at 212s the situation changes, the output changes and habituates again.
